NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 688,395, dated December10, 1901.

Application filed August 20, 1900. Serial No. 27,431 (No model.)

T at whom, it may concern:

Be it known that We, HOMER G. DAVIS and JOHN BAILEY, citizens of theUnited States, residing at Oonnellsville, in the county of Fayette andState of Pennsylvania, haveinvented new and useful Improvements inNut-Locks, of which the following is a specification.

Our invention relates to improvements in nut-locks; and the objects ofour invention are, first, to provide a nut-look especially adapted foruse on vehicles on the nuts used to retain the wheels on the axle,second, to aiford facilities for the proper retention of a nut on theaxle of a vehicle, and, third, to provide a new article of manufacturein a nut-lock simple in construction and easy of operation. Weattain'these objects by the mechanism, arrangement, and combination ofparts illustrated in the accompanying drawings, in which Figure 1 is aface view of an axle-nut, showing our inventionv in connectiontherewith.

Fig. 2 is a sectional view of the above, showing the details of ourinvention.

Similar letters refer to similar parts in both views.

The parts A and B represent an ordinary vehicle-axle nut, and O theouter end of an ordinary vehicle-axle, onto which the nut referred to isscrewed.

It is a well-known fact that the nut A B frequently accidentally worksoff of the axle O in backing the vehicle or otherwise to the damage ofthe vehicle and endangering life and limb. To prevent this, we providethe nuts with a locking device consisting of the stationary member E,secured at one end to the body of the nut, the other end being providedwith a hinge-joint, into which a movable member D is journaled, the twoparts E and D being pivotally united by the pin I. It will now be seenthat the member D can be moved into alinement with the member E or It isapparent that the arm D can be turned in the pivot I to stand parallelwith the member E. The nut A B can then be run on the axle G to thepoint desired, being careful that the recess in the point of the axlewill be opposite the arm D. Said arm is then brought toward the axleuntil it stands at right angles to the member E, when the outer point ofD will have entered the recess in the axle, thus securely locking thenut on the axle, as can be seen.

To retain the member D in contact with the recess in the axle or toretain it in alinement with the member E, we provide a flat spring Fparallel with'E, so that it will continually press upon the square endof D near the joint, thus gently retaining the arm D in an open orclosed position.

It is evident that changes in and modifications of the device hereinshown and described may be made without departing from the spirit of ourinvention or sacrificing any of its advantages.

Havingdescribed our invention, what we claim as new, and desire tosecure by Letters Patent of the United States, is-

' In aunt-lock, the combination of anut provided with a stationarymember permanently secured to the nut, a movable member pivoted to thefree end of the stationary member, a spring parallel to the stationarymember and adapted to secure the movable member in its operativeposition and a recess in said nut in which the movable member is adaptedto fit, with a bolt provided with a recess to secure the free end ofsaid movable member when the recesses register.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
